Using Genealogical Concordance and Coalescent-Based Species Delimitation to Assess Species Boundaries in the Diaporthe eres Complex.

ABSTRACT: DNA sequence analysis has been of the utmost importance to delimit species boundaries in the genus Diaporthe. However, the common practice of combining multiple genes, without applying the genealogical concordance criterion has complicated the robust delimitation of species, given that phylogenetic incongruence between loci has been disregarded. Despite the several attempts to delineate the species boundaries in the D. eres complex, the phylogenetic limits within this complex remain unclear. In order to bridge this gap, we employed the Genealogical Phylogenetic Species Recognition principle (GCPSR) and the coalescent-based model Poisson Tree Processes (PTPs) and evaluated the presence of recombination within the D. eres complex. Based on the GCPSR principle, presence o
